Internal/External Infrastructure Penetration Testing
Internal and external infrastructure penetration testing are two essential methods used in cybersecurity to evaluate the security of a company’s network and systems. These tests involve simulating real-world attacks to identify vulnerabilities, assess the effectiveness of security measures, and recommend necessary improvements.
Internal infrastructure penetration testing focuses on evaluating the security posture of a company’s internal network, systems, and resources. It involves testing from inside the network, mimicking potential attacks by threat actors who have already breached the perimeter. The goal is to understand how an attacker could exploit vulnerabilities from within and gain unauthorized access to sensitive information or disrupt operations.
External infrastructure penetration testing, on the other hand, assesses the security of a company’s external-facing network infrastructure. It simulates attacks initiated from outside of the network, just as a real attacker would. The objective is to identify vulnerabilities and weaknesses that could be exploited by malicious actors to gain access to the company’s assets or compromise its systems from the internet.
Wireless Penetration Testing
Wireless penetration testing is a method of assessing the security vulnerabilities in a wireless network. It involves a systematic and controlled approach to identify any weaknesses in a wireless network’s security defenses.
During a wireless penetration test, a trained professional, referred to as an ethical hacker or security consultant, will simulate real-world attacks on the wireless network to identify any potential vulnerabilities. This may include exploiting weak passwords, using unauthorized access points, or intercepting wireless traffic.
To conduct a wireless penetration test, specialized tools and techniques are utilized. These may include wireless network analyzers, packet sniffers, and password-cracking tools. The penetration tester will also follow a predetermined methodology, which typically includes reconnaissance, scanning, exploitation, and reporting.
It is important to note that wireless penetration testing should only be conducted by trained professionals who have obtained the necessary permissions and have the necessary expertise in wireless network security. It is a complex process that requires in-depth knowledge and understanding of wireless technologies, networking protocols, and potential attack vectors.

The goal is to identify any security flaws, such as SQL injection, cross-site scripting (XSS), insecure user authentication, or inadequate access controls.
Mobile Application Testing
Mobile application penetration testing is a crucial process in developing and maintaining mobile applications. It involves assessing the security of a mobile app by identifying potential vulnerabilities and weaknesses that malicious attackers could exploit.
Mobile application penetration testing aims to simulate real-world attack scenarios and identify any vulnerabilities that could lead to unauthorized access or misuse of sensitive user data. This testing helps to ensure that the app is secure and resilient against potential threats, providing a safe and reliable user experience.
During penetration testing, a team of experienced security professionals uses various techniques and tools to assess the app’s security controls, communication protocols, data storage, and authentication mechanisms. They attempt to identify weaknesses that could allow an attacker to gain unauthorized access to the app or compromise user data.
Build and Configuration Review
A build and configuration review is a critical step in the software development process. It involves thoroughly examining and assessing the codebase and configuration of a software application or system before it is released to users or deployed in a production environment.
During a build and configuration review, a team of experienced developers and engineers assess the quality and reliability of the codebase and configuration files. They identify potential issues, such as bugs, vulnerabilities, or performance bottlenecks, and propose solutions or improvements.
The review process typically involves a series of steps, including code walkthroughs, static code analysis, and performance testing. Code walkthroughs involve a detailed examination of the source code to identify any logical or structural issues in the implementation. Static code analysis uses automated tools to analyze the code for potential bugs, security vulnerabilities, and coding best practices violations. Performance testing involves evaluating the performance and scalability of the application under different load conditions.
The goal of a build and configuration review is to ensure that the software application or system meets the highest quality standards and is ready for production deployment. By identifying and addressing any issues or weaknesses in the codebase and configuration, the review helps to minimize the risk of software failures, security breaches, or performance issues.
Social Engineering
Social engineering penetration testing is a valuable tool for organizations looking to strengthen their security measures. It involves evaluating the organization’s susceptibility to social engineering attacks, which are attempts to manipulate individuals into divulging sensitive information or performing actions that can compromise the organization’s security.
During a social engineering penetration test, trained professionals simulate real-life scenarios to assess the organization’s vulnerabilities. This may include phishing emails, phone calls, or physical attempts to gain unauthorized access to restricted areas. The goal is to identify weaknesses in the organization’s security protocols and provide recommendations for improvement.
To conduct a social engineering penetration test, it is essential to establish a clear scope and objectives. This includes defining the specific tactics that will be employed, the individuals or departments to be targeted, and the level of access to be obtained. It is important to keep in mind that the test should be conducted with the organization’s consent and in accordance with legal and ethical guidelines.
Cloud Penetration Testing
Cloud penetration testing involves simulating real-world cyber attacks on the cloud environment to uncover potential security flaws. This can include testing for weak passwords, misconfigured access controls, and vulnerabilities in the underlying infrastructure.
The process typically involves a team of skilled security professionals who use automated tools and manual testing techniques to identify any weaknesses in the system. They will attempt to exploit vulnerabilities to gain unauthorized access, gather sensitive information, or disrupt the cloud services.
By conducting regular cloud penetration testing, organizations can identify security vulnerabilities before hackers do, allowing them to address and mitigate potential risks proactively. This helps to ensure that sensitive data and resources stored in the cloud are adequately protected.
Agile Penetration Testing
Agile Penetration Testing is a systematic approach to assessing the security vulnerabilities of a software system in an Agile development environment. Agile methodologies, such as Scrum or Kanban, strongly emphasize delivering frequent updates and iterations of a software product. This fast-paced and iterative approach requires a corresponding security assessment process that can keep up with the rapid changes and deliver timely and accurate results.
Traditional penetration testing is often conducted as a one-time, point-in-time assessment. However, this approach is not sufficient in an Agile development environment where new features and updates are frequently added. Agile Penetration Testing involves integrating security assessments into each iteration of the Agile development process. This allows for early and continuous identification of security vulnerabilities, ensuring that they are addressed promptly.
Agile Penetration Testing involves a combination of manual and automated testing techniques. It includes vulnerability scanning, code review, threat modeling, and penetration testing. The goal is to identify software system weaknesses and provide actionable remediation recommendations.
The Role of Red vs Blue Team in Penetration Testing
White box vs black box vs grey box pen testing
White box penetration testing
White box penetration testing, also known as transparent box testing, is a comprehensive and advanced security assessment technique that thoroughly examines a system’s internal structure and architecture.
Unlike black box testing, where testers have no prior knowledge of the system’s inner workings, white box testing allows testers to access the system’s source code, network diagrams, and other relevant documentation. This level of access enables testers to fully understand the system’s design, identify potential vulnerabilities, and develop targeted strategies to exploit them.
Black box penetration testing
Black box penetration testing is a type of security assessment that aims to evaluate the vulnerabilities of a system or network from an outsider’s perspective. This approach is called “black box” because the testers have little to no knowledge of the system’s internal workings. This allows for a realistic simulation of a real-world attack scenario where the attacker has limited information about the target.
Grey box penetration testing
Grey box penetration testing is a type of security assessment that combines black box and white box testing elements. In grey box testing, the tester has limited knowledge about the system’s or application’s internal workings. This approach simulates an attacker’s perspective who may have some insider knowledge or access to certain information.
During a grey box penetration test, the tester is usually provided with certain information about the target system or application. This may include architecture diagrams, network maps, or source code snippets. This limited knowledge allows the tester to understand the system better and identify potential vulnerabilities from both an external and internal perspective.
One of the advantages of grey box testing is that it can provide a more realistic assessment of the security posture of a system or application. By having access to some internal information, the tester can focus their efforts on areas of the system that are more likely to be vulnerable. This approach can help identify vulnerabilities that may not be apparent in a black box test, where the tester does not know the system’s internal workings.
